Abstract
The utility model relates to a piano, in particular to a keyframe module positioned in the piano and used for placing black and white keys. The technical scheme is that the digital piano keyframe module is characterized by comprising a keyframe module body. A black and white key reset elastic part, a digital piano counter weight clamping rod, a digital piano circuit board installing rod and a clamping block are arranged on the keyframe module body. An insertion groove and an insertion block are arranged on two sides of the keyframe module body respectively, and a horizontal fixing plate installing area and a longitudinal fixing plate installing area are arranged on the keyframe module body on the other side of the keyframe module body. By adopting the technical scheme, the keyframe module overcomes the shortcomings in the prior art, and the novel digital piano keyframe module is reasonable in structure, convenient to install and light in weight.
Description
Technical field
The utility model relates to a kind of piano, refers to especially the keyframe module of the arrangement white-black key of piano inside.
Background technology
As everyone knows, existing piano kind is a lot, the keyframe structure of its positioned inside white-black key of various pianos is also different, the keyframe that they install white-black key is one-piece construction, usually need to install how many white-black keys, how long keyframe is just made, and there are following problems in such keyframe: 1, keyframe is heavy, causes the weight of whole piano large; 2, the piano that model is different need to be done different keyframves, has so greatly increased technical risk and cost; 3, because keyframe is long, mould and equipment requirement are very high.
The utility model content
The utility model overcomes the problem that prior art exists, and novel digital piano keyframe module a kind of rational in infrastructure, easy for installation, lightweight is provided.
Realize above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of digital piano keyframe module, it is characterized in that: include the keyframe module body, be provided with the white-black key return springs on the described keyframe module body, digital piano balance weight body clamping bar, the digital piano circuit board is installed support bar and caking block, the both sides of described keyframe module body are respectively arranged with inserting groove and grafting piece, and described keyframe module body is positioned at and is provided with horizontal fixed head installing zone and vertical fixed head installing zone on the opposite side that white-black key is installed.
By adopting such scheme, we just can be piano key shut die blocking, and we just can reduce technical risk and the cost of exploitation greatly according to any assembly unit of the length of piano keyframe like this, have reduced the requirement of production equipment; Laterally fixed head installing zone and vertical fixed head installing zone can conveniently add fixed head between the keyframe module body in addition.
Further setting of the present utility model is: on the horizontal fixed head installing zone of described keyframe module body with it the fixed head that is provided with of one settle piece, settle on the piece and be provided with threaded hole, also be provided with on the described arrangement piece for the spacing stopper slot of fixed head; Be provided with the fixed head locating shaft on vertical fixed head installing zone of described keyframe module body; Described keyframe module body is positioned at and is provided with the axle of pegging graft for an end of white-black key on the side that white-black key is installed; The inserting groove of the both sides of described keyframe module body and grafting piece are dovetail slot and dovetail inserted block.
The purpose that further arranges is that product is made on the basis of superior performance, and cost performance is higher comparatively speaking, wherein is provided with the axle of pegging graft for white-black key in the keyframe module body, and key and keyframe are with axle and axis hole location like this, and precision is high; Inserting groove and grafting piece are dovetail slot and dovetail inserted block, and this mode is pegged graft firmly convenient.
Below in conjunction with accompanying drawing the utility model is further described.
